To al? whom it may ,con-cern:

Ee it known that i., GOTTLOB Hmmm.

engineer, e subg'eet 0i" the German mperor, residing mb lzi ieppeziieuetr.. se, Stuttgart, Germany, have invented cert-ein new mid useful improvements in Electromagiieticaiiy- Gpereted nterrupter lgniving .ieviees ier Explosiorifiioters; and i do hereby declare he ioiiewiiig te be i'uii, dem', and exact description of the invention., such esjviii enebie others siiiiedin the art ze which ii appertsliiis to make and use he seme. l

The inventie11-re'etes to eiecrcmegnevieally ecuziized spar mg rie-vices for the ignition ci' expiosieii engines. in such devices iii is very importent to ebeiii the maximum of magnetic effect Wiich een "be produce-1i with in mi exceedingly limited space and with a loes 0i' electrical energy es smell as possible, because the latter reduees the effect ci the ignii-ing spades, particularly et siow speeds.

The invention consists iii giving'tiie core 'ci' ifiie eiee'trorimgiiei; auch a Shape es jte produce the best e'iee by disposing beth poles and the armature inside ci' the coil, one side of die piveted armature forming .e bridge between the' poles and the other eide forming .fui extensieii which constiiutes the interi'upter oi the circuit for 'producing the sparks. TWith reger the magnetic lose it is of advantage i0 make the gap between Jthe poles es smell es possible. According to this invention i make. the opposite polarand armetureesrirfziees iueeiigf s icing as 'the armature itself. Consequently iii@ cressesec tion ier the passing ci iines ei' ,i'eree Wiii be .much increased. The iie lines ei' force may b cviinder 'which alii-zest e the windings 0i /iie ceii. The invention eisocciilpriees certain modi cetioiis by W 'he megiietie resieeiiee between the peres @Td 'iie armature is im ther reduce i,

neic material. The armature e, which is pivemiiy mounted atf, has an exteiisio.- g which constitutes lieA interrupter of the cir @uit ior producing the sparks. Figs. 2 and 3 show, 'imiiar ceiistrueticiis, but with the difference 'that the 'polar Surfaces are formed. curved7 for a'erdiiig e, greater surface 'fer the passage @i the lines of force. The same reeuit is 0b mined in the Constructions. shown iii.
